Kisspeptin-10 Nasal Spray — 10mg

Kisspeptin-10 is the shortest fully active fragment of the kisspeptin family, a decapeptide acting at the KISS1R receptor. It is studied extensively in KISS1R and GnRH signalling research. This nasal atomiser format supplies the same research-grade Kisspeptin-10 stocked in vial form.

SHIPPED UNMIXED — AND WHY THAT MATTERS

Durham Peptides does not ship pre-diluted nasal sprays. Peptides in solution are materially less stable than in lyophilized form, so a bottle that is mixed at the warehouse begins degrading the day it is filled and continues to do so in transit and in storage. Instead, the lyophilized peptide and the diluent travel separately and the researcher reconstitutes on arrival — which means undegraded lyophilized material and a known, controlled in-use window rather than an unknown one.

Every nasal spray ships with sterile water preserved with 0.3% potassium sorbate, supplied specifically for this format. No separate bacteriostatic water purchase is required.

FORMAT

• Ships unmixed — stable lyophilized material, not a solution degrading in transit

• Diluent included — sterile water with 0.3% potassium sorbate, no separate purchase needed

• Defined receptor target — an agonist at KISS1R (GPR54) with an extensive published research base

• Verified identity — MS-confirmed against a third-party lab report you can check independently

WHAT RESEARCHERS LOOK AT

• KISS1R (GPR54) receptor activation in preclinical models

• Downstream GnRH signalling

• Whether the 10-residue fragment reproduces full-length kisspeptin activity

• Post-reconstitution stability across the in-use window

DOES THE NASAL SPRAY COME PRE-MIXED?

No, and that is deliberate. Peptides are materially less stable in solution than in lyophilized form, so a pre-diluted bottle starts degrading the day it is filled. Durham Peptides ships the lyophilized peptide and the sterile diluent separately so the researcher reconstitutes on arrival — undegraded material, and a known in-use window rather than an unknown one.

DO I NEED TO BUY BACTERIOSTATIC WATER SEPARATELY?

No. Every nasal spray ships with its own diluent — sterile water preserved with 0.3% potassium sorbate, supplied specifically for the atomiser format. This differs from the lyophilized vials in our catalogue, which are reconstituted with bacteriostatic water sold separately.

NASAL SPRAY VS VIAL — WHICH SHOULD I CHOOSE?

Both supply the same research-grade Kisspeptin-10. The vial — Kisspeptin-10 — 10mg — is the flexible option, since the researcher chooses the reconstitution volume and therefore the working concentration. The nasal atomiser arrives with matched diluent included.

WHAT IS KISSPEPTIN-10?

Kisspeptin-10 is the shortest fully active fragment of the kisspeptin family — a decapeptide corresponding to the C-terminal active region of the KISS1 gene product, acting as an agonist at KISS1R (GPR54). It is studied extensively in KISS1R and GnRH signalling research.

HOW SHOULD IT BE STORED AFTER RECONSTITUTION?

Keep the bottle refrigerated at 2–8°C and protected from light both before and after reconstitution. Once reconstituted, use within an appropriate research timeframe — a peptide in solution has a materially shorter usable life than the sealed lyophilized material.

HOW IS IT SHIPPED IN CANADA?

Orders placed and paid before 4:00 PM EST ship the same business day via Canada Post Xpresspost with full tracking. Shipping is domestic from within Canada, so there are no customs delays or border holds.

IS THE COA VERIFIABLE?

Yes. Every batch is independently lab-tested with a unique report key you can confirm independently — see our guide on how to verify a lab report key.
